3. In the case of exponential type
• The number of all digits that can be specified by +1 is as follows. (Maximum: 24 digits)
When the number of digits below decimal point is "0" . . . . . . . . . . . .No. of digits ≥ 6
When the number of digits below decimal point is other than "0". . . .No. of digits ≥ (decimal digits + 7)
• Decimal digits that can be specified by +2 is 0 to 7 digits. Please set within the range of decimal digits
≤ (total digits - 7).
For example, in the case of all digits of 12 and decimal digits of 4, when -12.34567 is specified, the data after
is stored as follows.
